“Beck revisited his slacker-punk roots with the songs he wrote for Scott’s band Sex Bob-Omb; though they’re performed by Michael Cera and the other actors in the film…Meanwhile, Broken Social Scene are Crash and the Boys, the rival band whose “I’m So Sad, So Very Very Sad” lasts a whopping five seconds. Every part of the soundtrack shows how much care went into it, from choosing artists like Broken Social Scene and Metric to nod to the story’s Canadian setting, to the 8-bit version of “Threshold” that reflects Pilgrim’s immersion in video games. The sweetest detail may be the song that started it all: “Scott Pilgrim,” by the Canadian all-female band Plumtree from their 1997 album Predicts the Future, holds within it all the breathless true love and crunchy guitar goodness that sparked the comic.”–All Music Guide
